The PS Noise Harvester ruined the sound of my system.....put 2 in got worse....put 3 in.....returned them all. (also the light was annoying)
AC mains noise Borrowed noise sniffer and tested my AC lines...
I borrowed this AC line noise sniffing device (Blue Horizon Mains Noise Analyser) today. (Do not ask from where, I do not feel at ease saying.)
This device sniffs out noise and has a range of "000" to "999" and over that it just is "MAX".
So first test was kitchen light with wall plug. "784"
Kitchen outlet tied to refrigerator (frig ON) "MAX"
Bedroom wall nothing around in use "220" wow good number.
Furutech Duplex at amplifier "013*" WHAT!!!! yes "013". That is on a direct 44 ft extension cord from 20 amp wall outlet (also Furutech) * with the C7 to the noise sniffer one way, it is 13, other way it is 20. ALL the measurements change with reversing the noise sniffer AC plug, about the same amount each time)
That extension does have an additional Furutech duplex on the cord, six feet back of amp Furutech plugs end, and that duplex has two PS Audio Noise Harvesters. The wiring is a quad twist. and each side or pair is connected to one out side. so each Noise Harvester is on one half of the quad.
So I can say the PS Audio Noise Harvesters really DO a fantastic job!!!
The other similar line (from he same 20 amp outlet) does not have any Noise Harvesters on it. And with the stereo running, it has "297" noise level. However IF I do stick one PS Audio Noise harvester in an out 3 feet back ot the one the sniffer is in. The noise drops to "143". (I cannot leave the Noise Harvester or a pair in there due to it being in use, normally, plus adding them in where the noise sniffer is, seems to make the sound go too thin.)
Another major discovery is just HOW NOISY Digital equipment really is!!! I have my two CD changers plugged into a separate power conditioner. A PS Audio P-600.
Testing the PS Audio P-600 I own (tested at 60Hz) With nothing turned on plugged into the P-600 the baseline noise is "040" With one five disc CD changer turned on the noise level jumps up to "740" With the other one only on the nose is also "740" with both on the noise jumps over "MAX" This is with a PS Audio Noise Harvester plugged into the same duplex (on the back of the P-600) as the CD changer!
On the other hand.. The Marantz SA-10 is pugged into the Furman (also with a PS Audio Noise Harvester in same duplex and that area is "032". So SOME equipment is not spewing, and some is.
This is all I have learned in a half hour of fooling around.
